The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further argumentation in detail:
In the drawings, elec. vehicle electric tramsmission proving installation is mainly by constituting with lower module: tested motor and controller 1 thereof, coupler 2, rotational speed and torque tester 3, change speed gear box 4, mechanical inertia 5, dynamometer 6, Dynamometer Control device 7, central computer and data acquisition equipment, whole device adopts two-way to arrange, each module has and extraneous machinery and electric excuse, is responsible for the co-operative control on each road by central computer.When the elec. vehicle electric tramsmission is done performance testing, if the elec. vehicle of test is single motor-driven, can adopt wherein a road; If what the elec. vehicle of being tested used is that many motors or electric drive wheel drive, then can uses two-way simulating vehicle left and right transmission systems stressed, and finish loading co-operative control two-way by central computer.Central computer also is responsible for the monitoring of whole testing device, the signal that it is gathered comprises: by the electric current and the voltage signal of measured motor and controller 1, the rotating speed of rotational speed and torque survey meter 3 and dtc signal, the bearing temperature signal of change speed gear box 3 and the pressure and temperature signal of oil coolant, the signal that the bearing temperature signal of mechanical inertia 5 and Dynamometer Control device 7 provide, these signals by sensor with the form of 0～10V voltage by the data acquisition system collection, and handle by central computer, the mode of operation of the whole testing device form with chart is presented on the graphoscope.The loading of dynamometer is set by the Dynamometer Control device, and the error between setting value and the actual test value is done signal conditioning by central computer and obtained, and feeds back to Dynamometer Control device 7, realizes the accurate loading of elec. vehicle electric drive system.Utilize bus that each module is done data acquisition and condition monitoring, reduced the length and the quantity of signal wire (SW).
The inertia of proving installation loads and adopts mechanical inertia is main, the mode of electrical inertia compensation, and mechanical inertia can be adjusted, and loads different inertia according to different vehicles, and little inertia then adopts the mode of electrical inertia compensation.
3 matching effects of change speed gear box, measurement of power the equipment torque that can apply and rotating speed and the tested rotating speed of motor torque that can bear are mated mutually, its objective is that assurance can obtain thoroughly evaluating as the performance of electronlmobil electric tramsmission testing of electric motors and controller thereof.For example, in the low speed high torque characteristic of testing of electric motors, can accurately load in order to guarantee measurement of power equipment, can adopt the speedup function of change speed gear box, low-tach torque loads requirement to dynamometer thereby can reduce; When the high speed constant output characteristic of testing of electric motors, when rotating speed of motor is very high, when surpassing the range of speed that dynamometer can bear, can adopt the reduction of speed function of change speed gear box, so just can guarantee that the load that dynamometer applies is in optimum regime.After utilizing change speed gear box to finish rotating speed between tested motor and the measurement of power equipment and torque coupling, just can consider the loading of finishing under the prerequisite of converter speed ratio mechanical inertia, and do little inertia by electrical inertia and compensate.The principle that should guarantee in the test process is: consistent with inertia with the torque that this tested elec. vehicle electric tramsmission motor bears on the motor shaft when real road moves to the value on the motor shaft with torque conversion the inertia that loads, this principle is guaranteed by the central computer monitoring.Adopt the rotational speed and torque instrument accurately to measure torque and the rotating speed that loads on the live arbor.
